i have referred link link2 link3

make sure below mentioned points taken care: 1) wrong service enabled. make sure "google maps android api v2", not "google maps api v2" enabled , re-generate api key.

2) add following elements manifest. replace com.example.mapdemo package name of application.

3) use of correct certificate , key. release certificate, not work during debugging when run app on phone. have use debugging keystore certificate fingerprint instead.
